Lifters choice

Decided to upgrade lifters. Not really sure what lifters is right for my application.
So the heads are tsp prc 237 62 cc heads. .660 dual springs with 415 lb open pressure.
Motor is a balaced 370 nitrous race setup. I want to spin it up as far as I reasonably can. Not afraid to take it 8k. My balancer even balanced the flex plate and said it's good to 8500.
Light weight forged rods and pistons.
Cam is a bullet .625 .625 244/254 on a 114. Not sure how far that cam will get me.

Any suggestions on lifters?
Any ideas how far the cam will go?.
